I would like to create linear structuring element but at different angles, are there any functions in scikit that will readily achieve this? Thanks for any assistance.
If I understand correctly, you want to draw line segments with different slope. How about generating start and end points with length*sin(angle), length*cos(angle) and using `skimage.draw.line*`? On Feb 26, 2014, at 2:43 PM, Neil Isaacs <bluewap2@gmail.com> wrote:

I want to get back an array that I can pass to a filter or morphology function as a structuring element. Similar to morphology.square or morphology.disk. For a horizontal line the selem would be something like [1 1 1 1 1] and I could use eye to generate a selem at 45 deg angle but I was looking for an existing function that might return an array of ones at arbitrary angles. Looks like draw.line just returns pixel coords. On Wednesday, February 26, 2014 1:09:29 PM UTC-7, Johannes Schönberger wrote:

Looks like draw.line just returns pixel coords. You can index into an empty structuring element with those coordinates and set them to one. Regards Stéfan
